Changes of indoor climate by the adoption of retrofitted wood-burning stoves

More than 3 billion people in the world rely on local solid-fuels for domestic cooking and heating through inefficient combustion, causing indoor air pollution and overheating worldwide. Technological regimes were categorized in 18 popular stove models to describe how residential wood combustion is performed across the world. The stoves performance was traced through literature review, laboratory and field studies, according to the population´s income in 7 regions.This technological map revealed that 92% of the wood consumption occurs in the south (cooking) while the largest share of wood heating happens in the north. The adoption of new stoves can save 15-50% of fuel and reduce 2-25 times the daily indoor concentrations of fine particles when moving from traditional to improved/advanced stoves (nanoparticles). Ergonometric combustion chambers and proper exhausts are key-elements to delay biomass consumption, adjust heat/demand through air-staging and ensure the indoor climate performance of advanced stoves in future housing.
